What to expect from Elon Musk's Tesla announcement Wednesday night

Tesla CEO Elon Musk sure knows how to keep Tesla fans on the edge of their seats. 

A little over a week ago, Musk said that the company had a product unveiling coming on October 17. The day before the event, he pushed the reveal to this Wednesday, October 19, stating that the product still needed a few refinements. 

As planned, the unveiling will happen on Wednesday evening. Earlier in the day, Musk tweeted that the company would be posting information about the mysterious product at 5:00 pm PST and that he will host a media Q&A afterwards. 

Musk has kept mum about what the new product will be, only saying that it is "unexpected by most." But there's speculation that it could be Autopilot 2.0.

Autopilot 2.0 is the next generation of Tesla's semi-autonomous driving system called Autopilot. With Autopilot 2.0, Tesla is expected to add more sensors to its vehicles to give it more self-driving capabilities. 

Musk announced Tesla's Autopilot system in October 2014, but the system originally rolled out to users in October 2015. Tesla's next unveiling will come four days after the one-year anniversary of Autopilot's launch. 

Tesla quietly increased the price of its Autopilot system in August from $2,500 to $3,000. Just a few weeks later, the company rolled out its software update, Version 8.0, to give the car new features and functions.

In August, Musk also hinted that Tesla's autonomous tech would be here sooner than expected. 

"Autonomy is going to come a hell of a lot faster than anyone thinks it will, and I think what we've got under development is going to blow people's minds. It blows my mind," he said.
